Description

Technical Field

[0001] The present invention mainly relates to the technical field of guiding parts, and specifically relates to a guiding mechanism for metal parts used in injection molding. Background Technique

[0002] An injection mold is a mold that uses a concave mold and a convex mold to cooperate for cooling and forming. When injecting metal fittings, the metal fittings need to be installed in the injection mold. The best method is to place the metal fittings in the concave mold during mold injection. When the mold injection is completed, the metal fittings are installed in the injection mold.

[0003] However, the existing metal fittings need to be placed manually when placed in the concave mold, which leads to a reduction in injection efficiency. Therefore, a guiding mechanism for metal parts used in injection molding is needed. Summary of the Invention

[0004] The technical solution of the present invention provides a solution significantly different from the prior art in response to the prior art solution, and mainly provides a guiding mechanism for metal parts used in injection molding to solve the technical problems raised in the above background technique.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows: A guiding mechanism for metal parts used in injection molding, including a protective cover. On the left and right sides inside the protective cover, a concave mold and a convex mold are respectively arranged. An inclined plate is arranged between the concave mold and the convex mold, and the inclined surface of the inclined plate faces the convex mold. On the side of the inclined plate away from the convex mold, an installation cylinder is installed. On the side of the installation cylinder facing the concave mold, a plurality of installation holes arranged side by side up and down are opened. A guiding part is installed in the installation hole, and the guiding part is in contact with the concave mold. A first rack is installed on the side of the convex mold facing the concave mold. A pushing part is arranged inside the installation cylinder, and the pushing part is in contact with the first rack and the guiding part respectively.

[0006] Preferably, the guiding part includes a guiding tube. The guiding tube is installed in the installation hole. The end of the guiding tube away from the installation cylinder is in contact with the concave mold. A groove is opened on the circumferential surface of the guiding tube, and a second rack is slidably connected in the groove. The second rack is in contact with the pushing part.

[0007] Preferably, the pushing part includes two connecting rods. The connecting rods are rotatably connected inside the installation cylinder. A linkage part is installed between the two connecting rods. A first gear is installed on the circumferential surface of the connecting rod. The first gear meshes with the second rack. One end of the upper connecting rod passes through the installation cylinder and a second gear is installed. The second gear meshes with the first rack.

[0008] Preferably, the linkage part includes a sprocket. The sprocket is installed on the circumferential surface of the connecting rod, and a chain is meshed on the circumferential surface of the sprocket.

[0009] Preferably, a rectangular groove is formed at one end of the material guiding pipe away from the installation cylinder. An L-shaped block is inserted into the rectangular groove. Bevels are cut at both ends of the L-shaped block. An elastic member is installed on the upper surface of the horizontal portion of the L-shaped block. One end of the elastic member away from the L-shaped block is installed inside the material guiding pipe. A resilient member is installed inside the material guiding pipe. One end of the resilient member is in contact with the L-shaped block. The end of the resilient member away from the L-shaped block is installed at the top inside the protective cover.

[0010] Preferably, the resilient member includes a sealing pipe installed inside the material guiding pipe. A resisting rod is inserted into one end of the material guiding pipe. The resisting rod is in contact with the L-shaped block. One end of the sealing pipe away from the resisting rod extends above the installation cylinder. A sealing rod is inserted into the end of the sealing pipe away from the resisting rod. The end of the sealing rod away from the sealing pipe is installed at the top inside the protective cover.

[0011] Preferably, rings are installed on both sides of the installation cylinder. A support rod is inserted into the ring. The support rod is installed at the top inside the protective cover.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. While the punch moves towards the die, the first rack contacts the second gear and drives the connecting rod to rotate. Then, through the cooperation of the first gear and the second rack, the circular ring materials placed on the circumferential surface of the material guiding pipe are loaded, reducing the manual operation cost.

[0013] 2. By installing an inclined plate on one side of the installation cylinder facing the punch, after the circular ring materials are loaded, when the punch contacts the inclined plate, the inclined plate is extruded, causing the inclined plate to move towards the top of the protective cover, thereby avoiding affecting the contact between the punch and the die.

[0014] 3. By forming a rectangular groove at one end of the material guiding pipe away from the installation cylinder and arranging an L-shaped block in the rectangular groove, and a bevel is formed at one end of the L-shaped block facing outside the rectangular groove. After the inclined plate drives the installation cylinder to move upward, the sealing rod squeezes the internal space of the sealing pipe, causing the L-shaped block to move out of the rectangular groove to block the circular ring materials on the material guiding pipe and prevent the circular ring materials from falling.

[0021] Please refer specifically to the attached Figures 1-6, A material guiding mechanism for hardware parts used in injection molding, including a protective cover 1. On the left and right sides inside the protective cover 1, a female mold 5 and a male mold 8 are respectively arranged. The movement of the male mold 8 is controlled by a hydraulic system. An inclined plate 7 is arranged between the female mold 5 and the male mold 8. The inclined surface 18 of the inclined plate 7 faces the male mold 8. An installation cylinder 6 is installed on the side of the inclined plate 7 away from the male mold 8. Circular rings 21 are installed on both sides of the installation cylinder 6. A support rod 20 is inserted into the circular ring 21. The support rod 20 is installed at the top inside the protective cover 1. On the side of the installation cylinder 6 facing the female mold 5, a plurality of installation holes are arranged side by side up and down, and a material guiding pipe 9 is installed in the installation holes. The circular ring 21 of the material is sleeved on the circumferential surface of the material guiding pipe 9. The end of the material guiding pipe 9 away from the installation cylinder 6 is in contact with the female mold 5. Then, a groove is opened on the circumferential surface of the material guiding pipe 9, and a second toothed rod 3 is slidably connected in the groove. The second toothed rod 3 is in contact with the circular ring 21 of the material.

[0022] A first toothed rod 19 is installed on the side of the male mold 8 facing the female mold 5. Then, two connecting rods 14 are rotatably connected inside the installation cylinder 6. One end of the upper connecting rod 14 passes through the installation cylinder 6 and a second gear 16 is installed. The second gear 16 meshes with the first toothed rod 19. A sprocket 15 is installed on the circumferential surface of the connecting rod 14. The two sprockets 15 are meshed through a chain 17. Then, a plurality of first gears 13 are installed on the circumferential surface of the connecting rod 14. The first gears 13 mesh with the second toothed rod 3.

[0023] When the male mold 8 moves towards the female mold 5, the first toothed rod 19 is brought into contact with the second gear 16, driving the connecting rod 14 to rotate. Then, through the cooperation of the first gear 13 and the second toothed rod 3, the circular ring 21 of the material placed on the circumferential surface of the material guiding pipe 9 is fed. And when the feeding of the circular ring 21 of the material is completed, the male mold 8 contacts the inclined plate 7 and squeezes the inclined plate 7, causing the inclined plate 7 to move towards the top of the protective cover 1, thereby avoiding affecting the contact between the male mold 8 and the female mold 5, and further reducing the manual operation cost.

[0024] A rectangular groove is opened at the end of the material guiding pipe 9 away from the installation cylinder 6, and an L-shaped block 10 is inserted into the rectangular groove. Both ends of the L-shaped block 10 are cut with inclined surfaces 18. Then, an elastic member 11 is installed on the upper surface of the horizontal part of the L-shaped block 10. The elastic member 11 is a spring. The elastic member 11 is in a normal state. The end of the elastic member 11 away from the L-shaped block 10 is installed inside the material guiding pipe 9. A resisting rod 12 is installed inside the material guiding pipe 9. The resisting rod 12 is in contact with the L-shaped block 10. The end of the sealing pipe 4 away from the resisting rod 12 extends above the installation cylinder 6. Then, a sealing rod 2 is inserted into the end of the sealing pipe 4 away from the resisting rod 12. The end of the sealing rod 2 away from the sealing pipe 4 is installed at the top inside the protective cover 1.

[0025] By opening a rectangular groove at one end of the material guiding pipe 9 far away from the mounting cylinder 6 and arranging an L-shaped block 10 in the rectangular groove, a bevel surface 18 is provided at one end of the L-shaped block 10 facing outside the rectangular groove. After the inclined plate 7 drives the mounting cylinder 6 to move upward, the sealing rod 2 squeezes the internal space of the sealing pipe 4, causing the L-shaped block 10 to move out of the rectangular groove to block the annular material on the material guiding pipe 9 and prevent the annular material from falling.

[0026] The specific operation process of the present invention is as follows: A plurality of rings 21 without materials are sleeved on the annular surface of the material guiding pipe 9. Subsequently, the material guiding pipe 9 and the second rack 3 are installed in the mounting holes. Then, the hydraulic structure is started to push the punch 8 towards the die 5. Subsequently, the first rack 19 contacts the second gear 16 and drives the second gear 16 to rotate. The rotation of the second gear 16 drives the upper connecting rod 14 to rotate. The rotation of the upper connecting rod 14 drives the lower connecting rod 14 to rotate through the cooperation of the sprocket 15 and the chain 17. Subsequently, a plurality of first gears 13 installed on the annular surface of the connecting rod 14 cooperate with the second rack 3 to push the ring 21 material into the die 5.

[0027] As the punch 8 continues to move and contacts and squeezes the inclined plate 7, the inclined plate 7 drives the mounting cylinder 6 to move towards the top of the protective cover 1. When the mounting cylinder 6 moves towards the top of the protective cover 1, the sealing rod 2 moves into the sealing pipe 4 and squeezes the air. The air squeezes the abutting rod 12 to move towards the L-shaped block 10, causing the L-shaped block 10 to gradually extend out of the rectangular groove to intercept the ring 21 material and prevent the ring 21 material from falling off the material guiding pipe 9.

[0028] The above has described the present invention exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
